[0025] In order to drive the dredging rod 4, the inner wall of the ray hole 3 is rotatably connected to the surface of the fixed ring 42 through a bearing, and the end of the thrust spring 43 is fixedly connected to an extrusion ring 44, which is funnel-shaped. The extrusion ring 44 is used to extrude and guide the dredging rod 4, so that the dredging rod 4 can block the ray hole 3. A threaded hole is provided on the rear end surface of the connecting column 1, and the interior of the threaded hole is connected to the interior of the ray hole 3. The inner wall of the threaded hole is threadedly connected to an extrusion sleeve 45, and the extrusion sleeve 45 is threadedly connected to the inner wall of the connecting column 1 through the threaded hole, so that the extrusion sleeve 45 can be installed into the connecting column 1.

[0026] In order to store the dredging rod 4, the inner wall of the extrusion sleeve 45 is rotatably connected to the outer surface of the extrusion ring 44, and a storage groove 46 is provided on the inner wall of the ray hole 3. The opening of the storage groove 46 is connected to the interior of the ray hole 3 and the interior of the threaded hole. The dredging rod 4 is stored in the storage groove 46, so as to avoid the dredging rod 4 from obstructing the ray hole 3. A red light emitter 5 is fixedly connected to the surface of one end of the extrusion sleeve 45. The ray end of the red light emitter 5 is located inside the extrusion sleeve 45. The red light emitter 5 is used to emit light into the ray hole 3, so as to facilitate irradiation detection.

[0027] By installing a dredging mechanism inside the connecting column 1, the dredging rod 4 in the dredging mechanism is stretched straight inside the ray hole 3, and the dredging rod 4 is driven to rotate inside the ray hole 3 by the rotation of the extrusion sleeve 45, and then the outer surface of the electric dredging rod 4 scrapes the inner wall of the ray hole 3 and scrapes off the impurities in the ray hole 3, thereby making it easy to dredge the inside of the connecting column 1 and avoiding affecting the use.

[0030] When in use, the extrusion sleeve 45 is screwed outward, the dredging rod 4 and the connecting blocks 41 at both ends are stretched and straightened, the outer surface edge of the dredging rod 4 is aligned with the inner wall of the ray hole 3, and the extrusion sleeve 45 is stretched outward to further tighten the dredging rod 4;

[0031] The extrusion sleeve 45 is rotated. Under the action of friction, the extrusion sleeve 45 drives the dredging rod 4 to rotate through the extrusion ring 44. The dredging rod 4 drives the fixing ring 42 to rotate together through the connecting block 41. The dredging rod 4 rubs against the inner wall of the ray hole 3 while rotating, and scrapes off the impurities in the ray hole 3. The impurities in the ray hole 3 are poured out through the upright connecting column 1.

[0032] After the dredging is completed, align the dredging rod 4 with the receiving groove 46, insert the extrusion ring 44 into the ray hole 3, and the extrusion ring 44 squeezes the dredging rod 4 into the receiving groove 46. Rotate the extrusion sleeve 45 into the threaded hole to fix the dredging hole and the extrusion ring 44.
